accomplished by the application oi the air to the inaterial.

ln Figs. 3 and 4, l have shown, somewhat .diagrammatically, a ioriu or'jigging device to agitate the bags and also a iorrn o device fordischarging the same. 1 is an arm pivoted to the frame and having aforwardly projecting lower portion 2 attached to a cross-bar 3. Theremust be two or more el the arms 1, and the cross-l bar 3 is thusarranged at one side ol' the bags While they are beingfilled. and thisvrarm-end ,2 is at each end of the bracket 3", to which the arm 2 ispvoted and which is supported by the two, rollers 3b 3 which travelbetween the guidey rails 6 6. The bar 3 has throiiglit a rod 4 on whichare mounted within the bar 3 aserics of upwardly bent pusher fingers 55. A cross-rod 7 connects the two elbow crank levers iormed by the parts1 and 2, and this cross-rod 7 may be manipulated toinove the pusherfingers in or out to iorce the bags away from the filling tubes FP onwhich they hang. When they are forced from such tubes, they fall in theinclined position indicated in Fig. 3 against the back 8 oi the jiggingboard or frame. This back or traine-piece connects with the end-ij'ieees 9--9, 'which are mounted 'on the vertical parts VIT 1Q-10,which'are in turn supported by ,the pitman 1.1i-u Ll from the eccentricA12--12 on the shaft 13. Thus the ligging-board or frame is kept invertical motion. y v

The bottom oi the frame lll, on which the bags really rest, is hinged at15-15 so that itcan be swung down into the position shown in dottedlines in Fig. 3. A hole in the floor, at 16, permits the bags to dropthrough as they pass down the chute 17. ing from this .bottom 14, is thelever 18, with the treadle 19 hanging therefrom, so that the operatorcan easily restore the bottom to the position shown in'full lines in`Fig. 3. This bottom is held in such position by means oi the hooks20-20, pivoted at 2l to the fixed bar 22-22,

associated with the jigging board and held in locking position by thespiral spring 23. The upper end of the hook 2() lies in the path of thebar 3, so that when the latter has moved far enough in, as indicated indotted lines in Fig. 3, to tilt the bags over and free them irorn thetubes P, the hook will also be swung on its pivot and the bottom 14 willbe released so that the bags can iall down as above described. Theseparts, as above suggested, are to be taken. diagrammatic andtheir'paijts may be greatly varied without departA ing from the spiritel this part ol my invention. What is here important is a j'igging boardof such a nature that during a portion of the jigging process, the bagmay be free to hang on its filling tube, while during the remainder ofthe process it is supported onv thejiggingboard. lt is also important tohave some means ior pushing the bags off when they are filled. Thus un`i filled bags when put on the tubes Pl) with the bottom in the positionshown in dotted lines hang ireely and though the jigging board is stillbeing vertically moved, the bags arenot affected. When the jigging board.is thrown up into the position shown in full lines, it begins toiactupon the bags.

telerring toFigs. 5 and (i, l here show diagrammatical'ly a modificationoi parts of Fig. 2. For example, if in Fig. 2, no means be'shown forpushing the filled bags oil", they will bang there, and it would only beThe connection between the bar 3.

under certain special conditions or circumstances that 'they could bepushed ofi by the air\ pressure. I desire to combine plungers and an airdevice, sothat. the bags may be filled by air and then b e pushed ofi bythe plungeyrs. The pipe SA is changed somewhat in term and locatedbeyond the base-board A. This pipe is connected at its ends with arms SSl from the eccen tric-strap S2 on the eccentric S3, driven by the shaltl S4. The plungers S5 consist each of a long inwardly projecting.portion which is supported in the tube-like part SG on the base A, andthe projecting end of which is passed through the pipe S, being screwedso as to be air tight. This plunger S5 may be a tube with a small axialaperture S7 and it may be plugged at SS. A small perforation SJ in' thistube plunger within the pipe S, permits the air which is led to suchpipe S by hose connection SO to pass into the tube aperture S7, andthence out of the end of such tube plunger.

The use and operation oi my invention are as iollows:

When a given kind oi material is `to be filled it may be applied to thestorage hopper in suitable quantities. By the arrangement of the twoboard valves, attached to one and the saine operating arm, anintermediate set oi measuring compartments or hoppers may be produced.They, of course, may be dispensed with if they are unnecessary. When thearm is' thrown in one direction Vthe openings in the storage hopper areiree, and the material can flow thence into the meas` uring hoppcrsuntil all are filled. By reversing the arm the feed will be cut offbute-ach measuring hop-y I per will be connected with its appropriatedownspout. As soon as this is done the material begins to How down'thespout into the lower semi-tubularportion. Assuming that the bags lareall in position and are held there by the spiral spring, they may now befilled by turning the air valve and allowing a current of air to flowinto the pipe. Any desired pressure may be used as the case may require.This air escapes through the very small holes, lt, into the' back end'oieach of these semi-tubular parts whence it rushes ior Ward carrying astream of the material into the bag, and also blowing the chaff, dustand the like from the material up through the hood or d'ischarge-way,4A1. It will be understood that when the measuring hop'- `pers are filledthe lever is reversed to cut oft the supply'above and permit thematerial from each hopper to flow into its appropriate down-spout. Thevprocess of filling the bags will continue until each has lbeen filled,and the material has been entirely exhausted from each-of the measuringhoppcrs. .The lever can then be reversed and the bags be removed and newones be slipped onto the tubes while the. material is re-filling themeasuring hopper-s.

iisA

Oi course, it will be understood that the niaterial v can be supplied inany desired manner, and with or without measurement or by bulk orweight.' The essential point is that the material is fed by air pressureto the bag,vand that the chaff, dust and the like may be blown out ofthematerial without other contrivance than that here shown. In order toinflate the bags, or blow the sizing out o them, the air may be turnedon before the-supply of material is turned en. When thel jigging d eviceis used, the bags are pushed oli when 4filled in a group, and then, bydropping them down the hinged bottom, they will `all slide out onto thechute below and thus to the packing-tables. There are many kinds ol'bags used and some o them are so shaped that. when empty they are muchlonger thunwhen filled. For example, the Satchel bottom bags are of thisclass, and it is necessary, in order that such bags may be properlyfilled, that the bottom may be properly expanded by the materiel fromwithin before the jigging process begins. There muy be various reasonsfor this not necessarydiere to be dis'- cussed. In onyevent, with thedevice of Fig. 8, the,

bags are simply suspended from the filling tubes/'QQ und then suppliedwith a. certain quantity yof inatterinl. This drops down into the bag,expands the bottoni, and brings it into a. proper condition to restupon. the bottom of the )ligging-board. ',The operator may then throwthe bottom upmid thus the jigging is applied to the bags themselves."Some method of discharging they begs nutonnrticnlly er in groups isnecessary, because, to pull them off by'hand, would be too' expensiveand require too much time. f l

lfVith/regird to/the device of Figs. 5 nnd'iiLno such pushing-ofi'device ns than: shown HFigQS/is necesf sary for, when the bugs:ircdlleol7 theplunger will itself force material into the bugsuilicientlyto fill the'snnie and .cause ybzig to be pushed ofi of thetube. I I. It is obvious 'that 'I have shown the ports in Figs. 5 and Gdizigiznnmaticolly and it might be better to greatly/change these ports.The" openings from ther tube-like part `O into the hopper K ond thespout A1 should be controlled or of such size ns to permit.' the plungerto bring oboutthe described result.
